Colorants Assessment Methodology
The purpose of this document is to serve as supplemental guidance to the Cradle to Cradle Certified Product Standard, Versions 3.0 and 3.1 (the ‘Standard’). This supplemental guidance provides a customized methodology for the material health assessment of colorants, specifically textile dyestuffs and pigments. This methodology differs from the general Material Health Assessment Methodology (‘the Methodology’) for use with other substance types, but is aligned with the current practices used in product assessments for textile dyestuffs and pigments. Information in this document supersedes any conflicting information that may be present in the original Standard document, but only for the specific substance and material classes discussed.
